A little break in Firmware development to help my client, an IoT start-up, diagnosing The Popcorn Effect. Something I’ve never seen with my own eyes before. The Popcorn Effect is a direct consequence of Moisture entering the IC before the reflow process. A common problem in Electronics Manufacturing. Production and Testing It all started onContinue Reading The Popcorn Effect on MSL 1
As for many new starters with Cypress Semi, I didn’t really know the major differences between PRoC and PSoC 4 BLE. In fact I didn’t even realise there was a difference. Yes there is. Luckily enough it is very simple! Cypress PRoC vs PSoC 4 BLE Cypress’ PRoC (Programable Radio On Chip) can be seenContinue Reading Cypress PRoC vs PSoC 4 BLE
